Question 85001
The straight string of a kite makes a angle of elevation form the ground of 60 degrees. The length of the string is 400 feet. What is the the best approximation of the height if the kite?
----------
Draw the picture. Rt. triangle with hypotenuse = 400 
and ground angle = 60 degrees.
-----------
EQUATION. 
Let height be "x".
sin(60) = x/400
x=400sin(60)
x= 400[(sqrt3)/2]
x = 400*0.866025
height = 346.41 ft.
